AI-generated summary

In the command line, run your app in profile mode with the device ID 00008110-xxxxx. Perform various operations in the app, particularly those that may cause jank. Press Shift+M to generate a flutter_01.sksl.json file in the project's root directory. When packaging and uploading the IPA, add the command parameter --bundle-sksl-path flutter_01.sksl.json. It is recommended to capture SkSL shaders on an actual iOS device for best results. Shaders captured on a simulator may not work correctly on real hardware.

在命令行中#

在 profile 模式下运行你的 app
flutter run --profile --cache-sksl -d 00008110-xxxxx
00008110-xxxxx 是你的设备 id
在 app 中做各种操作，主要是可能会产生卡顿 (jank) 的那些
按下 shift+m (M), 这时候会生成一个 flutter_01.sksl.json 的文件到项目根目录下.

Press M at the command line of flutter run to write the captured SkSL shaders into a file named something like flutter_01.sksl.json. For best results, capture SkSL shaders on an actual iOS device. A shader captured on a simulator isn’t likely to work correctly on actual hardware.
在打包 ipa 上传时，增加命令参数: --bundle-sksl-path flutter_01.sksl.json
